This isn't our product. We have a similarly named product, but it's a printable water soluble stabilizer - Stick 'n Stitch. As a matter of fact...we have a free template download of a page of these stickers that you can print out and keep. The beauty of using Stick 'n Stitch to print the target stickers, is that if you forget to remove them they dissolve away in the first washing. The ones in that pack do not. https://sulky.com/stick-n-stitch-8-12-x-11-printable-sheets
The template for the stickers is listed in the description there.
The purpose of the stickers is to precisely mark the position for the beginning of your embroidery. If you're off a 1/2 inch or so, you can move your hoop into that precise position under your needle.
